PyQt5之QThread线程模块

一、QThread

1、继承QObject

# -*- coding: utf-8 -*-
from PyQt5.QtCore import *


class MyWorker(QObject):
    def __init__(self):
        super(MyWorker, self).__init__()

    def doWork(self):
        # do something
        pass


if __name__ == '__main__':
    t = QThread()
    w = MyWorker()
    w.moveToThread(t)
    t.start()

2、继承QThread

# -*- coding: utf-8 -*-
from PyQt5.QtCore import *


class MyThread(QThread):
    def __init__(self):
        super(MyThread, self).__init__()

    def run(self):
        # do something
        pass


if __name__ == '__main__':
    t = MyThread()
    t.start()

二、QRunnable

# -*- coding: utf-8 -*-
from PyQt5.QtCore import *


class MyTask(QRunnable):
    def __init__(self):
        super(MyTask, self).__init__()

    def run(self):
        # do something
        pass


if __name__ == '__main__':
    t = MyTask()
    pool = QThreadPool.globalInstance()
    pool.start(t)

三、QtConcurrent

      本处详细查看《QtConcurrent详解》

def fun(param):
    # do something
    pass


if __name__ == '__main__':
    p1 = '..'
    p2 = '?'

    pool = QThreadPool()
    f1 = QtConcurrent.run( &pool, fun, p1)
    f2 = QtConcurrent.run( &pool, fun, p2)

    f1.waitForFinished()
    f2.waitForFinished()
